What is Vacuum Metalizing?
Vacuum metalizing is a process that allows you to create a layer of metal on a substrate, usually of another material. Also referred to as “vacuum deposition”, it involves heating the metal coating material until it vaporizes inside a vacuum chamber.
The lack of pressure in this chamber drives the metal’s boiling point downward. This allows the metal vapor to condensate and form a layer over the top of a substrate of your choice. For example, the semiconductor industry uses vacuum deposition to deposit copper interconnects on silicon.
The process may use various heating methods, including plasma beams, resistance heating, and electron beams. The end result is a metal layer that can range in thickness from a single atom through to several millimeters.
